The town was getting ready for the lottery. The boys went and gathered the stones . And, Mr. Summers was getting ready and making the name slips.
Tessie gets picked
All of the families are gathered together as they get ready to start. Mr. Summers starts to take attendants. Mr. Summers starts picking the family names and the Hutchinson family gets picked.
Tessie Hutchinson starts making excuses on why her family should not be the family who gets picked. She is saying that it is unfair. She was yelling things at Mr. Summers saying things like "You didn't give him enough time to take any paper he wanted. I say you. It wasn't fair!". She was just blaming everything on Mr. Summers.
Then, Mr. Summers starts picking the names for the individual family part to see which person in the family has to be the one who gets hit by the stones. Mr. Summers finally announced who it is, and it ended up being Tessie. Again she started saying that she shouldn't be the one who gets picked.
The pile of stones was ready from earlier. The villagers started walking over there to get the stones. Tessie was in the center of a clear space as the villagers started throwing the stones at her.
At the end Tessie dies. The lottery has been a tradition for them for a long time and they didn't want to break it. That is why Tessie had to get stones thrown at her head.
